Abstract

A pneumatic tire comprises a tread-reinforcing band (9) made of at least one spirally wound cord, wherein the band cord consists of materially identical high-strength high-modulus organic filaments, and the band cord is formed by first twisting each of filament bunches, subjecting the first twisted bunches to a dip-and-stretch treatment, and then twisting the treated bunches together, whereby the load-elongation curve of the band cord comprises a low-modulus zone and a high-modulus zone whose boundary point is in an elongation range of from 1 to 7%, and the ratio EH/EL of a nominal elastic modulus EH of the high-modulus zone and a nominal elastic modulus EL of the low-modulus zone is in a range of from 2.0 to 10.0. Therefore, high-modulus aramid cords, PEN cords and the like can be used to reduce the tire weight.
